Winter in Rovaniemi is cold - usually something between -5 and -25 degrees celsius. We have a lot of snow. The winters are dark and we have the so called "Kaamos", dark period when sun never gets above the horizon. This is because the Earth is tilted on it's axis: northern and southern areas are either really sunny or really dark, depending on the season. In the winter we have beautiful natural lights: the beautiful Aurora Borealis. Winter is from November to the half of April.
Spring is warmer than winter, from -8 to +8 degrees, (warmer in the end of the spring), but there's still enough snow! Springtime starts in the second half of April, and lasts until the first days of June. During the spring snow starts melting and sun starts shining more & more. Snow reflects the sun beautifully and there's light everywhere! Early spring is the best time to do wintersports. When it comes closer to June, snow has melted and the summer starts.
Summer is lovely. In the summer people get active. It's about +18 to +30 degrees warm. Usually it's sunny, but there can be cloudy summers too. In the midsummer Finland is best!!! People are active and happy and there's a big midsummer feast all over Finland (June 21st). Summer lasts from June till mid-August.
Autumn is a colourful season. All trees turn yellow and red, and the ground gets covered in berries and mushrooms. Also the grass-root plants get painted in red and brown. The weather can be from +18 to -8 celsius, depending on what stage of autumn we are. From mid-August to September the autumn is lovely, but October is probably the ugliest month of the year, because it's so dark, the leafs from the trees have dropped and the snow hasn't come yet. But the whole year apart from October is lovely!
The best time to come is either in March-April, or from late June to the mid-July.
